From continental to regional scales, the zoonosis alveolar echinococcosis (AE) (caused by Echinococcus multilocularis) forms discrete patches of endemicity within which transmission hotspots of much larger prevalence may occur. Since the late 80s, a number of hotspots have been identified in continental Asia, mostly in China, wherein the ecology of(More)
Astroviruses infect humans and many different animal species and are associated with gastroenteritis. Recent studies first detected the virus from bat species in Hong Kong. To understand astrovirus distribution in the wider region further, we examined the prevalence of this virus family in bat specimens collected from a large geographical region of mainland(More)
This paper introduces VeMAC, a novel multichannel TDMA MAC protocol designed specifically for a vehicular ad hoc network. The network has one control channel and multiple service channels. On the control channel nodes acquire time slots in a distributed way, while on the service channels nodes are assigned time slots in a centralized manner. VeMAC decreases(More)
Energy efficiency is a critical issue in mobile ad hoc networks (MANETs) for increasing the lifetime of the individual nodes as well as the overall network. In this paper, we propose a new energy-efficient broadcast protocol called EBOLSR, which adapts the energy-efficient OLSR (EOLSR) protocol to the broadcasting domain. In order to maximize the(More)
Wireless multihop networks, built with tactical radios, have limited bandwidth; yet often need to support bandwidth-intensive 1-to-many and many-to-many communications. Efficient routing proposals for wireless broadcasting have been suggested in the literature, and more recently the use of network coding to efficiently support such communication patterns.(More)
In this paper, we propose an adaptive medium access control (MAC) solution for a fully-connected mobile ad hoc network (MANET), supporting homogeneous best-effort data traffic. The MAC scheme achieves consistently high network performance by adapting to the ever-varying network traffic load. Based on the detection of current network load condition, nodes(More)
Over the course of several million years, the eukaryotic gut symbionts of lower termites have become adapted to a cellulolytic environment. Up to now it has been believed that they produce nutriments using their own cellulolytic enzymes for the benefit of their termite host. However, we have now isolated two endoglucanases with similar apparent molecular(More)
